I wish it was possible to give a neutral rating. Sadly it is not possible,
The puzzles are quite easy to solve. Getting perfect solutions is sometimes fairly hard (and I tend to only go for perfect solves in games like this, so that's good(ish)).
But the difficulty does not come from inherently difficult puzzles. It comes from the wacky mechanics of the equipment. E.g. you can use a bow to shoot at a chair and the arrow will land one square in front of the chair. Since movement gets stopped by picking up an arrow (otherwise you walk until you hit a wall - without being able to stop in between) you can then later use that spot to change directions. Okay, figuring out something like that for the first time is hard. But just because you would never expect things to behave this way. In a way it is almost more lateral thinking than puzzle solving. And when you figured it out your reaction is not "Oh, what a smart solution to a beautiful puzzle". Your reaction is "Oh, that's dumb, but okay..."
It is not a bad game. It is just not very good either. I will finish it, but then never pick it up again.

Great game. Simple but challenging. Knowing there is a quicker way to solve each puzzle will bug the crap out of you.
